camel http4 producer encodes an array data to the http uri parameter as comma separated

Issue

camel http4 producer encodes an array data to the http uri parameter as comma separated.

camel route

    .setHeader(Exchange.HTTP_QUERY, simple("ids=${header.ids}"))
    .to("http4://localhost:8181/sample/test/hello");

http request

http://localhost:8181/sample/test/hello?ids=[Bob, Nancy, David]

How to make the uri parameter as multi-values?

http://localhost:8181/sample/test/hello?ids=Bob&ids=Nancy&ids=David
